How is halite mined?
Regional SpecificsUnderground Halite deposits are often mined by drilling wells into the salt layer, and bringing in hot water which quickly dissolves the salt into a brine. The brine is saturated with dissolved salt and is then pumped out. The brine evaporates and the remainder salt crystallizes and is harvested. Where can halite be mined? Halite
Which clastic sediment has the smallest grain size?
Regional SpecificsShaleShale has the smallest grain size. Shale is made mostly of clay-sized particles and hardened mud. When sediments settle out of calmer water, they form horizontal layers. Which type of clastic sediment has the smallest particle size? Clay is the category of clastic sediment with the smallest particle size. Which grains are smallest? Teff is
What is the viscosity of andesitic lava?
Regional Specifics102 to 107 Pa s102 to 107 Pa s, which is due to a wide range in phenocryst contents from 0 (phenocryst‐free andesitic melt) to ∼50 vol % (50 vol % rhyolitic melt + 50 vol % phenocrysts). Does andesitic lava have low viscosity? Siliceous Lava Flows – High viscosity andesitic and rhyolitic lava flows,
What is the crystal form of a mineral?
Regional SpecificsCrystal form refers to the geometric shape of mineral crystals. Crystal form is caused by the symmetrical, three-dimensional arrangement of atoms inside the mineral. Not all minerals form perfect visible crystal shapes. Some crystals are too small to see. What are the 6 crystal forms of minerals? The six crystal families are triclinic, monoclinic, orthorhombic,
What countries are in the Great Rift Valley?
Regional SpecificsIn Kenya, Uganda and the fringes of South Sudan, the Great Rift runs along two separate branches that are joined to each other only at their southern end, in Southern Tanzania along its border with Zambia. The two branches are called the Western Rift Valley and the Eastern Rift Valley. How many countries are in
What is Richter scale in geography?
Regional SpecificsThe Richter scale measures the magnitude of an earthquake (how powerful it is). It is measured using a machine called a seismometer which produces a seismograph. A Richter scale is normally numbered 1-10, though there is no upper limit. What is the Richter scale simple definition? Richter scale (ML), quantitative measure of an earthquake’s magnitude
